Ecumenical Patriarch Kyriakos II

Ecumenical Patriarch Kyriakos II (552-606) was the Ecumenical Patriarch of Constantinople from 595 to 606, succeeding Ecumenical Patriarch Ioannes IV and preceding Ecumenical Patriarch Thomas I.

Biography
Kyriakos was appointed as the Ecumenical Patriarch of Constantinople in 595 AD under Emperor Maurice of Byzantium. He shared Maurice's unpopularity, and in 602 Maurice was deposed and executed by Ecumenical Patriarch Thomas I. Kyriakos forced Thomas to confess his Orthodox Christian faith, and Kyriakos died in 606.
